Oh, no -- the ultimate diet book would be accompanied by something like what Baum had in his Oz books: a pill that provided a full, balanced, healthy meal, so you didn't have to waste time eating but got a proper diet. (His Professor Wogglebug also developed pills for each school subject, so students could spend the whole school day engaging in sports.) Remove taste from the balance, and everyone will eat well! And you'd wash it down with water, of course.
